A prominent medical school conducted a study that concluded adults with high blood pressure who consistently ate small amounts of low sugar dark chocolate experienced a significant reduction in blood pressure. As the study was being reviewed prior to publication in a medical journal, it was discovered that the Jershey Chocolate Company provided substantial funding for this research. a) Identify any bias in this study.
b) Is it reasonable to conclude that adults with high blood pressure who consistently eat small amounts of low sugar dark chocolate experience a significant reduction in blood pressure?

Step-by-step explanation:

In the given question, the study was performed to analyse the effect of eating dark chocolate on the person with hypertension or increased blood pressure.

a) The biasness in the experiment could be that the funding for the study has been provided with a Private Company which mainly aims at selling their product.

b) The research is reasonable as it has been proved that eating a small amount of Dark chocolate can help cardiovascular disease like hypertension or increased blood pressure.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
